the revival badge has this description: Answered more than 30 days later as first answer scoring 2 or more. What does "as first answer" mean in that sentence?
It doesn't mean that my answer is the first answer because I've gotten it for non-first answers
@YEZ it binds to "scoring 2 or more". That is, it doesn't matter if there were other answers already; so long as yours was 30+ days after the question was asked and was the first one to reach a score of 2, you get the badge.
And to anticipate your next question, yes it's a little unusual to merge an older question into a newer one, but we felt that the newer question was asked better so that's why we did it this way.
